  1. Motions that occur in the saggital plane and frontal axis
    flexion and extension
  2. Motions that occur in the frontal plane and saggital axis?
    abduction/adduction, radial/ulnar deviation, inversion/eversion
  3. Motions that occur in the transverse plane and vertical axis
    internal/external rotation, horizontal abduction/adduction, supination/pronation, right and left trunk rotaion
  4. Define osteokinematics
    • relationship of bony movement
    • discusses bony movement of a joint
    • visible movement of a joint
  5. Define arthrokinematics
    • relationship of joint surface movement
    • must have arthokinematic motion to have osteokinematic motion
  6. Define the axial skeleton
    cranium, face,vertebral column, and sternum
  7. Define appendicular skeleton
  8. List the functions of the skeletal system
    • Support- for soft tissues of the body
    • Movement - bones serve as levers and joints as fulcrum
    • Protection - vital organs
    • Mineral Storage - calcium and phosphorous
    • Provide shape
  9. Define a synovial joint
    • diahthrosis
    • plane, hinge, pivot, cndyloid,saddle, ball and socket,
  10. Define a non-axial joint
    • plane joint
    • relatively flat joint surfaces
    • glide over one another
    • no degrees of movement
    • example: intercarpla or interstarsal joints
  11. Define uniaxial
    • one plane, one axis
    • one degree of freedom
    • hinge or pivot
    • ex: elbow, knee, or interphalangeal
  12. Define biaxial
    • 2 axes, 2planes
    • condyloid or saddle
    • ex metacapophalangeal, and radiocarpal
  13. Define Triaxial
    • 3 axes, 3 planes
    • ball and socket
    • hip and soulder
  14. Types of arthrokinematic motion
    • spin - rotary movement, one surface is fixed and the other surface spins on it
    • Roll - one joint surface rolls on another
    • Glide - Linear movement, parallel motion
  15. Convex-concave law
    • concave joint surfaces move in the smae direction as the joint motion
    • Convex joint surfaces move opposite the direction of the moving body segment
  16. List the functional Characteristics of Muscle Tissue
    • Irritability - react to stimnulus
    • Contractility - ability to shorten or contract
    • Extensibility - stretch
    • Elasticity - rocoil
  17. Active Insufficiency
    • when a muscle reache3s a point where it can't shorten any farther
    • occurs when muscles are contracting
  18. Passive insufficiency
    • When a muscles can't be elongates any farther without damage to the fibers
    • occurs to the muscles being stretched
  19. Types of Muscle Contraction
    • Isometric- fixed, no motion
    • Isotonic - concentric shortening
    • eccentric- lengthening
  20. Roles of Muscles
    • Agonist- muscles or muscle group that causes the motion
    • Antagonist - muscles tat performs the opposite motion
    • Cocontraction - when agonist and antagonist contract at the same time
    • Stabilizer- muscle group that supports or makes firm, a part and allow the agonist to wrok more efficently
    • Neutralizer - prevents unwanted motion
    • Synergist - works with other muscles
